This place is pretty awesome. It may be my favorite outdoor shopping area (I refuse to call it a mall) in Phoenix. There are so many wonderful world-class and local stores and restaurants (Macy's, BCBG, Apple, Escada, MAC, Teavana, The Limited, Williams-Sonoma, Christopher's Crush, CPK, Seasons 52, Capital Grille, Zinburger, cosmetics, jewelry, clothing for the whole family, electronics,books, gifts, flowers, cards, shoes, pretty much anything you would need and a bunch of stuff you just want!) Also, they have fun events (movies in the park, Dining after Dark, Live Music @ UNION, cooking classes, store events, etc.) so make sure you check out their calender of events because it seems like they always have something going on during the evenings).
If you don't use the valet parking or the free parking area, don't forget to validate!
